Powers:Kubik's power seems virtually infinite by the standards of the human beings of Earth.

Bio:Kubik's ultimate creators were the mysterious otherdimensional entities known as the Beyonders. The Beyonders study the development of life in Earth's dimension. As one of their experiments, they allow vast energies to enter the Earth dimension through interdimensional portals created through the use of a certain kind of force field. Such energies can be entrapped within a matrix of force fields that form a perfect cube. The result is the entity known on Earth as a Cosmic Cube. A Cosmic Cube will alter reality according to the desires of its wielders. However, a Cosmic Cube is also a living being in embryonic form. Eventually it develops its own consciousness patterning it after the consciousness of the sentient being with whom it is in mental and physical contact. Finally, the Cosmic Cube will become a mature sentient being capable of independent will and action. Kubik is one such cube.

The cube that would evolve into Kubik was "created" by Advanced Idea Mechanics, a subversive organization that supplies advanced weapons to other cabals such as HYDRA and the Secret Empire. Both MODOK and the Red Skull used it primarily as a mind control device. Later, Set the Serpent God used it to try to enter the Earth-616 reality. The demon was defeated however, and the Cube fell into the hands of a man named Bernard Worrell, who became the new leader of a splinter cell of AIM scientists.

Wielded by Worrell during a battle with Captain America, the Cube was affected by the man's hatred and aggression, and began to distort. At this moment, the Shaper of Worlds arrived under orders from the Kree Supreme Intelligence to nurture the Cube and stop it from destroying reality, as the Shaper almost had when it was a cube controlled by the Skrull Emperor. Allowing Captain America to hold the cube, the Shaper could tell it was impressed by the man's heroism and courage, and then took it from Earth to further raise it.

Some years later, during the Secret Wars, Kubik and the Shaper arrived in the Beyonder's pocket universe to confront the cosmic being. Now morphed into a humanoid form, Kubik showed the Beyonder and the Molecule Man that they were both parts of an incomplete cube, and merged their powers to form a new being called Kosmos.

Kubik was last seen as overseer of Kosmos' guidance. His current whereabouts are unknown.
